Automated Distributed Control Systems (DCS) tsis tu ncua kho cov txheej txheem hloov pauv raws li cov ntaub ntawv tiag tiag - lub sijhawm, kom ntseeg tau tias cov kev mob zoo raug tswj xyuas txawm tias thaum lub sijhawm hloov pauv lossis cov khoom siv raw hloov pauv. Qhov no txo cov neeg ua haujlwm kev vam khom, tshem tawm cov kev cuam tshuam qeeb, thiab txo qis qhov tshwm sim ntawm qhov tsis zoo sib txawv.
Safety Instrumented Systems (SIS): Tiv thaiv kev xwm txheej ua ntej lawv nce
Thaum cov txheej txheem automation tsom rau kev ua haujlwm thiab kev ruaj ntseg,Safety Instrumented Systems (SIS)yog tsim tshwj xeeb los tiv thaiv cov xwm txheej txaus ntshai los ntawm kev nce mus rau qhov xwm txheej loj.
Safety Instrumented Systems ua hauj lwm ntawm nws tus kheej los ntawm lub ntsiab tswj system thiab yuav tshwm sim thaum predefined kev ruaj ntseg txwv yog tshaj. Hauv cov nroj tsuag caustic soda, SIS lub luag haujlwm tseem ceeb heev vim muaj cov tshuaj corrosive thiab cov pa roj tawg.
| Hazard Scenario | SIS Function | Kev tshwm sim |
|---|---|---|
| Overpressure hauv electrolyzer | Kev kaw thaum muaj xwm ceev | Tiv thaiv rupture |
| Chlorine leakage | Tsis siv neeg cais | Tiv thaiv cov neeg ua haujlwm |
| Hydrogen buildup | Venting & kaw | Kev tiv thaiv tawg |
| Kev ua kom txias tsis ua haujlwm | Load txo | Cov cuab yeej tiv thaiv |
Los ntawm kev pib kaw, kev rho tawm, lossis lub tswb nrov, SIS cov tshuab tshem tawm kev cia siab rau tib neeg lub sijhawm cov tshuaj tiv thaiv, uas yog qhov tseem ceeb tshwj xeeb hauv siab - nrawm lossis siab - cov xwm txheej txaus ntshai. Qhov no txo qis qhov tshwm sim ntawm kev puas tsuaj loj heev.
3.Real-Lub Sijhawm Saib Xyuas thiab Kev Pom Zoo Digital: Txo tib neeg raug
Automation kuj txhim khu kev nyab xeeb los ntawmtxo qhov xav tau ntawm phau ntawv kev cuam tshuamnyob rau thaj chaw muaj kev phom sij. Los ntawm tiag tiag - lub sijhawm saib xyuas thiab cov chav tswj hwm hauv nruab nrab, cov neeg ua haujlwm tuaj yeem saib xyuas cov haujlwm cog qoob loo yam tsis muaj kev cuam tshuam ncaj qha rau cov tshuaj corrosive lossis siab - cov cuab yeej muaj kev pheej hmoo.
Cov txiaj ntsig ntawm Tiag -Kev Saib Xyuas Sijhawm
